It’s the best 270 bucks I’ve ever spent. No, really, the hype is real. Go buy one, if you can find it. Sell a vital organ if you have to. I can’t overstate how simple this pedal is. It’s a “MORE” button for your amp. If you like the sound you’re getting, it’s just going to give you more of what you like. If you don’t, then it’s going to give you more of what you hate. The gain gets a little grainy at the upper limits, but that seems to be the case with most low-medium gain ODs. The treble is just an ever-so-slight filter that helps you put in or take out a little presence when engaged. The output... is what it says on the tin. Honestly... it’s going to be an always-on pedal for me. Into the squeaky clean channel of my DSL40C, I can coax a little bit of natural overdrive and a touch of the Klon’s “simulated power amp saturation” sound for a nice off-clean with a just a little bite with pick attack. But... when I put my OCD between the Klon and my Marshall, it becomes an absolute high-gain monster. Super tight, punchy low end; great clarity and note separation; lots of that sizzling high end with a touch of roll-off that lets the bite through but keeps the harshness out. Together, the OCD and the Klon respond extremely well to pick attack and the volume knob. I love DSL40C and my SG, but there’s always been a little something missing. The OCD helped me get closer, but not quite. I plugged this in and immediately thought “This is it.” I’m now getting the very best tone at any volume that I’ve ever gotten out of any piece of gear I’ve ever owned, period. This isn’t conformation bias: I honestly expected not to really love the thing, I just bought it because of its relative rarity and it’s increasing value. Forget increasing value. This thing is meant to be played, and play it I most certainly will. Time will tell if the honeymoon lasts but man. This thing just sings and sings and sings.
